2 Claims. (Cl. 198-210) The present invention relates to lamp makingmachinery and, more particularly, to an automatic hot cut last flarereclaiming machine.

A are is a piece of glass tubing on which a ilangeor flared portion isformed for subsequent sealing to a vitreous envelope of an incandescentlamp or the like. Flares are made on automatic flare machines whereinthe standarized precut lengths of glass tubing are placed in suitableholding means mounted on a rotatable carrier. The end of the tubingisthen heated andflanged, the length of the are to be cut from thetubing is gauged, and the are is cut from the tubing all by automaticmeans.

cullet, scrapped, and fed to a glass furnace for re-` processing. Thispractice not only involves additional expensive handling and processingbut does not untilize the last flares to the best advantage.

Hence, it has been found advantageous, according to my invention, toprovide an automatic hot cut last or overlong sized flare reclaimingmachine which reduces the excessive waste of last flares, is automaticin its operation, and requires only the periodic attention of a machineattendant to supply a new batch of long flares to the hopper. j

My last are reclaiming machine comprisesl essentially a rotatable turretmoved from station to station by an indexing mechanism and carrying aplurality of,vfor example, eight flare holding heads. At Station 1, thelast are to be reclaimed is automatically fed by a stem machine arehopper into the now open flare holding jaws. At Station 2, a gauging orvertically positioning unit positions the flare in the now closed jaws.At Station 3 a rotating Oxy-hydrogen fire from a rotating burner heatsthe are and thereby sets up a sharp strain therein at the desiredcut-olf line. Between Stations 3 and 4, the flare contacts a cold wheelwhich completes the strain therein as a further step toward severance atthat line. Adjacent the wheel a knock-off rod projecting from a culletdischarge chute engages the lower portion of the flare and effectscut-off at the line of strain. At Stations "4 and 5 a stationary burnerglazes the cut-oli end of the flare. At Station "6 a similar stationaryburner completes the glazing and also anneals the bottom portion of theare. At Station 7 a plurality of stationary burners maintains thecut-olf end of the flare in a semi plastic condition and a reciprocatingreamer forms a very slight are therein. At Station 8 the are-holdingjaws areY automatically opened, and the reclaimed flare is droppedthrough a discharge chute into a circular annealer from where they areperiodically transported to the stem making machines in the conven- Ytional manner,

ICC

In its general aspect, the present invention has as an objective theproduction ,of an automatic hot-cut last flare reclaiming machine whichreduces the waste of the last ares, is automatic in 'its operation, andrequires only the periodic manual loading of the flare hopper.

Other objects of the invention will become-apparent to those skilled inthe art to which it appertains as the description proceeds. Y

Referring to the drawings in detail, and particularly to Figs. 1 and 2,the hot cut last flare reclaiming machine of my invention is designatedgenerally by the reference numeral 10. The machine 10 has a rotatableturretlZ, provided with a plurality of flare-holding heads 14, eight,forl example, in the showing of Fig. 1, and movedthru a plurality ofstations by lan indexing mechanism 16 (Fig. 2),` which in turn isoperated by driving mechanism 17 of the machine 10.

At Station l a last (overlong) flare 18, hereinafter referred to asalflare 18, is fed automatically from a stem machine flarehopper,20,into a pair of normally closed flare holding jaws 22 (Figs. 3and'4) of a head 14, which Astrain in the arc 18 at the gauged cut-ctiline.

The other endlof thelspring 9 0 is suitably secured to the spacing member 84 at theleft hand end of the slot Sti, as viewed in Fig. 3. The left the" l owvdwell of the stationary jaw-operating cam 23. ,Itwillbe .understoodthat this upper end `11'1of the lever :110 swings back andfor'th-in thejawoperating slot 53 hand end of spacing member 84 (as viewed n Fig. 3)is horizontally bifurcated and projects beyond the bracket 57 and theslide plate- 80,-;--and carries a cam roller 92 therein.

As shown in Fig. 4 the jaws'22 on the forward end of each head 14 arepivoted (on the bottom portion 8S of the bracket 57 by means of pinsr94) betweentheslide plate and the bottom portion 85 of the bracket 57and are free to swing laterally between their open and closed positions.The slide plate 80 is provided with jaw-operating slots 96 in which ajawoperating pin 98 (projecting upwardly from each jaw 22) extends. Anactuating spring 100 extends from one jaw to the otherl and maintainsAproper grip on a flare 18 when held therebetween.

It will be understood that as a head 14 indexes `from Station 7,4 thevendreaming or forming station,to StationrS, the-discharge`stationfthecani roller --92 rides upthe gradually inclinedportion of:the stationary `cam 23, as shownrin Fig. l, thus moving theslide plateYStland the slotted spacingmember 84 atlixedtheretofoutwardlyin theybracketj57 or to thewright whenviewed in Fig. y

roller'10 6 (Fig. 2) for engagement `v/ithfthe jaw operatingmechanism'cam 74 on the indexing and timing shaft 70. A'connecting'rod108'join's` 'the'other Vend of the 'leveril 102 to a second bellcrank"`1eve`r 110, suitably pivoted on the pedestal S5.' The upperoroperating end 111 ofthe lever 110 is formed to be engaged by the -camto'move tocarry said roller"92"fromthe" high dwell to providedinthe'stationaryv cam 23 at Station 1.

As 'thefhead 14 indexes from Station-8, the discharge station, toStation 1, the loading station, the upper end '111.of the lever '114i(Figi 4) is in its 'forward position andfunctionsas a continuationofithe highdwell of stationary cam After a are 1 8 has been delivered tothe now open jaws 22 at Station 1, the cam 74 is itimed so that rollerl106 leaves the highv dwell of the 'jaw-operating mechanism cam 7i-andmoves to theright,

.as viewed in 2, thiiscausing theconnecting'rodl to move upwardly,andhence the upperend 111 of 44the Vbell crankilever to swing to theleft-(when viewed in Figs/2 and .3), into'the rearwardportion of the jawoperating slot 58 ofthe stationary cam 23.* ln this positiontheuppei end111 of vthe lever 110 coincidesA with the low dwell of the stationarycam v23, asshown in Fig. 2.

y it-will befunderstood that the retreating motion Vor inward movementaxially toward the center of the turret 12 of the upper end 111 of thelever.110 and the compressive action of the spring 90 against theforward portionvof the spacing member 84, causes the plate S0 and thespacing member 84 to follow said upper end 111 of the lever 110. Theinward motion of the slotted plate 80 closes the jaws 22 about thepositioned are 18 located thereat.

Vertcally positioning unit The vertically positioning unit 26, shown inFigs. 1, 2 and 5, has an air cylinder 112, adjustably mounted on abracket 114 extending upwardly from the top of the table 56. Thiscylinder is connected by means of a line 116 (Fig. 2) to a two-way airvalve 118 xed to the bottom platform 61 of the table 56, adjacent theshaft 60 of the reducing unit 62, and the two-way air valve operatingcam 76 on indexing and timing shaft 70 of the machine 10. A cam lever120 (Fig. 2) is pivoted on an upward extension 122 of the twoway airvalve housing, and carries, on its free end a cam roller 124 (Fig. l).The roller 124 is maintained in engagement with the operating cam 76 bya spring-biased air valve release button 126, which contacts theunderside of the cam lever 120. An operating rod 128 of the air cylinder112 depends from a vpiston in saidcylinder and carries aflare-positioning button or disc 130.

It will be understood that as a head 14 is indexed from Station 1, theilare loading station, to Station -2, the gauging station, that theroller 124 on the lever 120 is in engagement with a low dwell of the airvalve operative cam 76 and hence the air valve 118 is closed. Since noair is flowing through the air cylinder 112, the positioning button 130is in its upper or normal position. At a predetermined time after thearrival of a flare 18 in the head 14 at Station 2, the cam roller 124engages the high dwell of the cam 76, thus depressing the release button126 of the air valve 118 opening said valve, and causing, through airpressure, the downward movement of the operating rod 128, and moving thepositioning button 13) thereon into engagement with the top of the are18 held in the jaws 22 of the head 14.

The lowermost position of the button 130, shownrin Fig. 5, -isdetermined by the position of the air cylinder 112 on the mountingbracket 114. The are 18 in the jaws 22 is pushed downwardly the properdistance for effecting the desired cut-off of the are 18 undergoingreclamation.

Oxy-hydrogen burner and rotating mechanism At Station 3, the verticallyadjustable Oxy-hydrogen burner 28, shown particularly in Fig. 6, ismounted on and radially off-set from a hollow shaft functioning as thefuel supply pipe 132. The adjustable pointed strainproducing flame fromthe burner 28 is directed at the desired cut-off point, as predeterminedby the vertically positioning unit 26 at Station 2. The burner 28, andhence the iiame therefrom, rotate in a circle about the stationary flare18 held in the jaws 22 of the head 14. The burner 28 is rotated by theburner-rotating mechanism 30.

The burner rotating mechanism 38 (Figs. l and 2) has a gear 134 affixedto the fuel supply pipe 132,for engaging a horizontal driver gear 136(Fig. 2). This gear 136 is Xed to a vertical shaft 138 carrying a bevel`gear '140 on its lower end. A second bevel gear 142 on a horizontalshaft 144 meshes with the bevel gear 140 on the left hand end of theshaft 144, as viewed in Fig. 2. A bevel gear 146 on the opposite end ofshaft 144 enwho@ I Cold wheel The cold wheel 32, shown in Figs. 1, 2 and7 is a disclike body desirably formed of steel and having an annularknife edge 150 (Fig. 7). It is adjustably mounted on a vertical shaft152. This shaft 152 is mounted on the outer extremity of a rotatablewheel arm 154. The arm 154 is pivoted on a station-ary arm 155 aflxed toa suitable column or pedestal 156 (Fig. l). This pedestal 156 is mountedon the top of the table 56, as by means of brackets. An angle iron 158,secured to the stationary arm 155 has its free flange disposed generallyparallel to the rotatable arm 154. A -bolt 160 extends through the arm154 and the free flange of the angle 158, and carries a compressionspring 162 thereabout. A nut on the outwardly extending portion of thebolt 160 maintains the desired compression on the cold wheel 32 forproperly contacting the strained cut-off line on the flare 18.

The wheel 32, and more particularly the knife edge 150 of the saidwheel,- is kept cold by droplets of water deposited thereon (Fig. 7)from an outlet 164 of a cold water supply (not shown).

1f the contact between the strained cut-olf line on the flare 18 and thecold knife edge 150 of the wheel 32 is still insuicient to sever theundesired cullet portion of the flare 18, this cullet portion comes intocontact with the knock-off rod 34 mounted on the cullet discharge chute36 therebeneath. The head 14, and the now deculleted are 18 continuecounterclockwise to Station 4 At Station 4, 5, and 6 the glazing burners38, 40 and 42, respectively similar to burner 40, shown in Fig. 9, heatthe cut-olf end of the deculleted ilare 18 to smooth or glaze any sharpor ragged edges thereon. These burners, and the rotating burner 28 arefed from a gas supply system 166 (Fig. 1).

Gos supply system The gas supply system 166, shown particularly in Figs.l and 2, comprises oxygen and hydrogen manifolds 168 and 170respectively mounted as by means of brackets,

gages another bevel gear 148 on the indexing and timing As the head 14indexes ntreinstation 3 vtoStation l75 on the top of the table 56, aseries of mixers 171 thru 174 connected to the manifolds 16S and 170,and a series of flexible connections 175 thru 179 for carrying the oxy-4hydrogen gas mixture from the mixers to the burners `28, 38, 40, 42 and45, respectively.

Reamer unit The reamer unit 46, shown in Fig. 10 and located at Station7 has an air cylinder 180 adjustably mounted, as by means of brackets,on a suitable pedestal 182. This cylinder is connected by a flexible airline 184 to the air valve 118, and carries a conically-ended reamer 186on its operating ro-d 188. The stationary burners 45 disposed about theglazed cut-olf end of the flare 18, maintain a semiplastic conditionthereat which facilitates the forming operation.

It will be understood that as a head 14 indexes to Station 7 the two-wayvalve 118 is closed and the reamer 186 is in its normal or lowerposition. IAs the two-way air valve operating cam 76 opens the valve118, compressed air is admitted into the air cylinder 180, thus pushingthe reamer 186 into contact with the glazed and still plastic cut-offend portion of the ilare 18. At a predetermined time before the end ofthe operating portion of the index period, the cam 76 closes the valve118 and the reamer 188 reciprocates to its normal position.

Stem machine flore hopper The flare hopper 20, shown only partially inFigs. 1 to 4, inclusive, is a conventional stem-machine ilare hopperhaving `a discharge chute 190. This chute k19|) has a hinged end portion192 on its side rail facing Station 2 and anr L-shaped stationary endportion -193on`its assied othe'sid'e rail. After 'the ilare '18hasvbe'en delivered into the jaws 22 of a head 14 of Station1,the'are`is held simultaneously -byfthe jaws and the end portions 192and 193 of the guide rails of the chute 190. As the head 14 indexes fromStation l to Station 2, the hinged end'portion '1'92f'swi`ngs outwardlyto release the flare 18 fromthe chute 190. Spring action in the hingedportion 192'returns lsaid end portion to its normal orloading'position'afterthe are 18 has leftth'e chute 190. i AY stemmachine hopper feeddrivingm'e'chz'trii'srriD 194, the essential parts ofwhich are shown in Pig. 2, has a bellcr'ank lever '196 pivoted on .abracket 198 which depends from the underside of the top'ofV the table-56. The lower end of the lever 196' carries a cam 'roller 200 whichengages the stem machine flare hopper operating cam 78. A connecting rod202, part of which is shown, in Fig. 2, is secured to the? other end ofthe lever 196. The remainder of the connecting mechanismfor transmittingmotion from the cam 78 to the stem machine flare hopper 20 is not shown.

i Operation As each head 14 of the machine V10 indexes from Station 8,the -discharge station, to Station 1, the loading station, the camroller 92 on the inner end of the head 14 is riding on'the high dwell'ofthe stationary cam 23, and hence the jaws y22 remain in the openposition. When the headreaches Station 1, the roller 92 engages: theupper end 111 of the bell crank lever 110 of the 'hare holding jawoperating mechanism 24 and the jaws remain open'`suiciently long for aflareV 18 to be delivered from the stem machine flare hopper 20 thru thedischarge chute 190 into position on the end portions 192 and 193 of thechute rails.

At a predetermined time, the roller 106 on the bell crank lever 102 ofthejaw operating mechanism 24 engages the high dwell of the jawoperating mechanism cam 74 and the upper end 111 of the bell crank lever110 moves into the' rear portion of the operating slot S8 provided inthe stationary cam 23, thus permitting the jaws 22 to close about theare 18. The head 14 then indexes from Station l to Station 2, thegauging station. At Station 2 the cam roller 124 on the end o'f thelever 120'of the gauging unit 26 rides up a raised portion of thetwo-way valve operating cam 76, thus depressing the air valve'releasebutton 126, actuating the air valve 118, andsimultaneously causing theflare positioning b1'1tton'13tl on" the endJ of the air cylinderoperatinglpistlonlZSto engage the upper end of the are 18, and'position' said ilare in the jaws 22 with the desired cut-oit line"aligned' with respect to the strain producing rotating lburner 28 atStation 3 and the cold wheel 32 andknock-ol'lrod 34 between Stations 3and 4.

At Station 3 the pointed llame from said burner 28 produces a'straininthe 'lower end of the flare 18 at the desired cut-oit line. Betweenstations 3 and"4 the 4strai'nediline on the flare 18 engages the coldknife edge 150 ofthe wheel 32,` thus completing thestrain at the li-neofcut-off. If'the cullet4 end of the are 18 is not removed V'by Contactwith the-wheel32,` the flare`18 then engages"'the knock-off rod 34 n`on`the lculletdischarge chute 36, and the cilllet portion of the flare isremoved therefrom. p

At Stations 4,"5 and 6 'the glazing burners 38, 40`and 42"'respectively,Vglazev the cut-olf end of the ilare 18,' and maintain said end oftheare 18 in a semiplastic state so that, upon indexing to Station 7, theplurality of stationary burners 4S situated thereat are able to maintainthe plastic condition on the end portion of theare 18,'which is requiredfor a slight flaring and rounding thereof.

AfterA the headv 14 has indexed to' Station ""7, 4the reamer unit 46 isoperated simultaneously with'the vertically"posit`i`orringunitf2atSt'ation2, by actiolro'f the twofway valve" ope"`ra'ti'ngcarrir`V76` "orl the Vindexing 'and timing shaft" 701 Air vpessureissimultaneously delivered to both of the units 26 and 46.
